COMBINATION DRINKING WATER AND ROOM COOLER Filed May '7, 1950 Patented Mar. 8, 1932 UNITED STATES PATENT OFFICE RUSSELL A. PICKENS, F FAIR LAWN, NEW JERSEY, ASSIGNOB TO SERVE INT OF NEW YORK, N. Y., A. CORPORATION OF DELAWARE COMBINATION DRINKING WATER AND BOOK COOLER Application filed May 7, 1980. Serial No. 450,868.

This invention relates to a cooler designed for cooling drinking water and the air within a room.

It is an object of the invention to provide a combination cooler of this character of compact construction which will not occupy more space thanis required by a cooler designed to perform one of these functions and at the same time to provide a room and water cooler which is simple and inexpensive to manufacture.

The invention will first be hereinafter more particularly described with reference to the accompanying drawings which form a part of this application and later pointed out in the claims at the end of the description.

In said drawings:

Fig. 1 is a front elevation illustrating one application of the invention;

Fig. 2 is a vertical section; and

Fig. 3 is a horizontal section.

Referring to said drawings in which the same reference characters are used to denote corresponding parts throughout the several views, indicates a cabinet having a lower machine compartment 11 and an upper refrigerating compartment 12 for the reception of cooling coils and a fan hereinafter more particularly described.

The upper compartment is surrounded by a wall 13 of insulating material and has mounted therein a water cooling coil 15 located in a narrow tank 16 centrally of said compartment and between chilling sections 14. The chilling sections are spaced to provide between the same warm air ducts or fines for the passage of air to be chilled, such air being admitted through the front of the lower compartment, which is provided with a reticulated screen or net work S. A deflector plate D preferably of sheet metal or the like material has its lower edge disposed at the loweredge of the front opening or screen S and extends upwardly and rearwardly over the compressor and motor in order to prevent heating of the air which enters the cabinet by such motor and compressor.

The upper surface of the refrigerating 50 compartment is inclined and is provided w a grilled opening 17 through which air may be expelled into the atmosphere of the room by the fan 18.

Beneath the chilling tank 16 in which the water coil is mounted, is located a wall of insulating material 19 to prevent the tank from being heated by warm air entering the cooler and bafiles 20 are disposed at each side of the member 19 to direct the warm air away from said tank. The water coil 15 has a connection 21 with a source of supply and a connection 22 with a drinking fountain nozzle 23, a valve 24 being inserted for controlling the operation of such drinking fountain. A waste pipe 25 serves to carry away water not consumed atthe fountain and may be connected with a waste or other discharge line, not shown.

A pressure line P connects the compressor of the machine 27 with the chilling sections 14 and a suction or return line B is also connected to such sections; an expansion valve 26 is inserted in the pressure line for a well known purpose.

The tank 16 is adapted to contain a water bath around the coil 15 through which the drinking water is adapted to pass. This water bath will be cooled by the chilling sections 14 and will maintain the drinking water within the coil 15 at the proper temperature. The water bath also will serve to prevent the freezing of the drinking water within the coil 15 and provide a reserve refrigerating capacity or prolong the refrigerating eifect so that water within the coil will always remain cold and in a liquid state.

In operation, the compressor of the machine 27 forces compressed gasified refrigerant through the pipe line P to the condenser C where it is condensed and such condensed liquid passes through the expansion valve 26 and expands in the chilling sections 14 cooling them. The liquid returns through the return lineR to the compressor. At the same time the fan 18 draws in and causes air to circulate through the device, the air entering through the grilled opening S in the lower compartment and be caused to pass upwardly over the shield between and around the chilling sections and is ex lled through the grilled opening 17. The an 18 is connected to operate with the motor for the compressor so that when one is shut down the other will also be shut down. The condenser C is of the water cooled type.

While I have shown cooling sections of one type, obviously they may be of another type if referred, for example, Murray.

t will be readily apparent that my device is particularly adapted for use where it is an advanta e to have both drinking water and means r maintaining the air within the room at a comfortable temperature, and therefore the invention is not limited to the use of thedevice merely in one embodiment, but various changes may be made without departing from the spirit of the invention.
